more lemmas about intervals

merged

refined parallel_proofs = 2: fork whole Isar sub-proofs, not just terminal ones; refined parallel_proofs = 3: fork terminal proofs, as poor man's parallelization in interactive mode;

join all proofs before scheduling present phase (ordered according to weight); tuned;

more explicit datatype result;

split dense into inner_dense_order and no_top/no_bot

move auxiliary lemmas from Library/Extended_Reals to HOL image

tuned (extend datatype to inline option)

prefer more systematic Future.flat;

more uniform Future.map: always internalize failure; added Future.flat as fast-path operation;

uniform treatment of global/local proofs; tuned;

tuned;

clarified Toplevel.element_result wrt. Toplevel.is_ignored;

more Thy_Syntax.element operations;

coercion-invariant arguments at work

constants with coercion-invariant arguments (possibility to disable/reenable coercions under certain constants, necessary for the forthcoming logically unspecified control structures for case translations)

simplified Proof.future_proof;

provide explicit dummy names (cf. dfe469293eb4);

discontinued empty name bindings in 'axiomatization';

provide common HOLogic.conj_conv and HOLogic.eq_conv;

just one HOLogic.Trueprop_conv, with regular exception CTERM; tuned;

discontinued obsolete 'axioms' command;

more robust build error handling, e.g. missing outer syntax commands;

eliminated legacy 'axioms';

marginalized historic strip_tac;

tuned proof;

tuned whitespace and indentation;

simplified imports;

load timings in parallel for improved performance;

proper place for cancel_div_mod.ML (see also ee729dbd1b7f and ec7f10155389);

parallel dep.load_files saves approx. 1s on 4 cores;

eliminated pointless re-ified errors;

merged

discontinued redundant 'use' command;

discontinued obsolete header "files" -- these are loaded explicitly after exploring dependencies;

discontinued obsolete 'uses' within theory header;

use lemma from Big_Operators

add inclusion/exclusion lemma

added lemma

merged

add wellorder instance for Numeral_Type (suggested by Jesus Aransay)

updated Toplevel.command_exception;

tuned;

tuned signature;

fork diagnostic commands (theory loader and PIDE interaction); explicit id for load_thy, for more robust Goal.fork accounting and commit for each theory -- NB: use_thys nodes become subject to Position.is_reported like PIDE document transactions; clarified Toplevel.command_exception vs. Toplevel.command_errors;

disallow shutdown from worker, which would lead to deadlock since the scheduler cannot terminate;

tuned 2464ba6e6fc9 -- NB: approximative_id is NONE for PIDE document transactions;

signal work_available should be sufficient to initiate daisy-chained workers, and lead to separate broadcast work_finished eventually -- NB: broadcasting all worker threads tends to burn parallel CPU cycles;

less eventful shutdown: merely wait for scheduler to terminate;

tuned messages;

tuned;

merged;

more explicit Goal.shutdown_futures;

reconsider 'export_code' as "thy_decl" command due to its global side-effect on the file-system;
